Interesting use of conditional comments:
If you use this HTML:
<!--[if IE ]> <body class="IE"> <![endif]--> <!--[if !IE]>--> <body> <!--<![endif]-->with CSS that looks something like:
div.foo { color: inherit; } .ie div.foo { color: #ff8000;then you get all of the advantages of using conditional comments to work around problems in Internet Explorer, without the extra HTTP request of an IE-only stylesheet.
